Commander wanted! Construct giant robots, build an army of a thousand Fleas. Move mountains if needed. Bury the enemy at all cost!

Simulated unit and projectile physics is used to a level rarely found in a strategy game.

The terrain itself is an ever-changing part of the battlefield.

Enjoy many hours of single player and coop fun with our campaign, wide selection of non-cheating AIs and a survival mode against an alien horde.

Zero-K was built for multiplayer from the start, this is where you can end up being hooked for a decade.

We are RTS players at heart, we work for nobody. We gave ourselves the tools we always wanted to have in a game.

Zero-K is a long term project and it shows, millions hours of proper multiplayer testing and dozens of people contributing ever expanding content.
